6 Claims. (Cl. 189-65) This invention relates in general to improvementsin window construction, and more particularly to improvements in sashconstruction for awning type windows.

The construction of an awning type window is such that the constructionof all of the sash thereof are identical with the exception of theuppermost sash which is special due to thenecessity of providing forengagement with a drip flange of the window frame. This requires themanufacture of different types of sash as well as the stocking thereof.

It is therefore the primary object of this invention to provide a sashconverting member which may be easily secured to a regular sash toconvert such regular sash to an upper sash whereby only regular sashneed be manufactured and stored.

It is to be understood that the term regular sash is to refer to allsash other than upper sash throughout the description of the invention.

Another object of this invention is to provide a sash converting memberfor converting regular sash into upper sash, the sash converting memberbeing so constructed whereby it may be easily slid into lockingengagement with a regular sash without requiring the use of any toolswhatsoever.

A further object of this invention is to provide a novel method ofconverting regular sash into upper sash, which method includes thesimple expediency of sliding a sash converting member into engagementwith a header of a regular sash.

With the foregoing and other objects in view, which will become moreapparent as the nature of the invention is better understood, the sameembodying novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated in theaccompanying drawings and defined in the appended claims.

In the drawings:

Figure 1 is an elevational view of an awning type window as viewed fromthe interior side thereof, the window 'having an upper sash utilizingthe sash converting member which is the subject of this invention;

Figure 2 is an enlarged fragmentary vertical sectional view takenthrough the upper portion of the window of Figure 1 along section line22 and shows the general cross section of the sash converting member andthe relationship thereof relative to the sash to which it is attached;and,

Figure 3 is an enlarged fragmentary exploded perspective of the sashconverting member and the sash to which it is intended to be attached, aportion of the sash being broken away and shown in section.

Referring now to the drawings in detail, it will be seen that there isillustrated in Figure 1 an awning type window which is referred to ingeneral by the reference numeral 10. The window includes a frame 12 inwhich are mounted upper and lower sashes 14 and 16.

The lower sash 16 is of a regular construction and includes a regularsash frame 18 having mounted there- 2,767,813 Patented Oct. 23, 1956"ice ina glazing 20. The sash frame 18 is formed of a pair of stiles 22connected at their upper ends by an upper rail 24 and a lower rail 26.

The upper sash 14 is formed of a regular sash 28 identical to the sash16 and a sash converting member 30.. The regular sash 28 includes aregular sash frame 32 having mounted therein glazing 34. In addition tojambs 36 and a lower rail 38, the sash frame 32 includes a upper rail40.

The upper rail 40 is generally H-shaped in cross section and includes anouter vertical flange 42 and an inner vertical flange 44 connected by aweb 46. The inner flange 44 projects above the outer flange 42 and hasan outwardly directed projection 48. The projection 48 is provided withan outwardly opening groove 50 whose lower extremity is coplanar withthe upper edge of the outer flange 42. The upper flange 42 is providedwith an inwardly directed projection 52 at the upper edge thereof.

The sash converting member 30 is of a generally L- shaped cross sectionand includes a vertical flange 54 l and ahorizontal flange-56. Thehorizontal flange 56 has depending therefrom an outwardly directed hook58. Also, the vertical flange 54 has an inwardly ofiset upper portion60.

When it is desired to convert a regular sash 28 into an upper sash, suchas the upper sash 14, the sash converting member 30 is driven endwiseinto the upper rail 40. When the sash 28 is provided with the sashconverting member 30, the horizontal flange 56 overlies the outer flange42 and has the free edge thereof seated in the groove 50. The verticalflange 54 extends upward- 1y as a continuation of the outer flange 42and the sash converting member 30 is retained in place by engagement ofthe hook 58 beneath the projection 52.

As is best illustrated in Figure 2, the offset portion 60 of thevertical flange 54 is so positioned whereby it is properly engaged witha weather stripping element 62 carried by a depending drip flange 64 ofthe window frame 12.

Since numerous modifications and changes will readily occur to thoseskilled in the art, it is not desired to limit the invention to theexact construction shown and described, and accordingly all suitablemodifications and equivalents may be resorted to, falling within thescope of the appended claims.

Having described the invention, what is claimed as new is:

1. The combination with a window structure wherein a plurality ofhorizontally swinging sash are disposed in a window frame and whereinthe sash are substantially identical in construction and with eachincluding an upper rail having inner and outer flanges, a strip slidablyengaging the upper rail of the uppermost sash and having lockingengagement with the rail in a manner to form an upper extension of theouter flange, the said strip adapted to have a weathering engagementwith a Weatherstrip carried by an overhanging drip shield formed uponthe window frame.

2. The device as in claim 1, wherein the flanges of the rail arevertically disposed, the inner flange being provided with an outwardlyfacing groove that is aligned with an upper edge of the outer flange,the outer flange having an inwardly directed projection along its upperedge, the said strip being L-shaped and including a vertical flange anda horizontal flange, the said strip being disposed in overlying relationto the outer flange of the rail and with the horizontal flange engagingthe said groove, the said strip forming an upper extension for the outerflange of the rail and means formed on the horizontal flange forinterlocking engagement with the projection of the outer flange.

3. The m ination with a window having .a frame and a plurality ofsubstantially identical sash horizontally pivoted in the frame and witheach sash including an upper rail having inner and outer flanges, meansdetachably connected with the upper rail of either sash whereby toconvert such sash to an upper sash, the inner flange having a forwardlyopening groove and 'the ,outer flange having an inwardly directedprojection, the said means comprising an L-shaped member having avertical flange and a horizontal flange, the horizontal flange havingits marginal edge seated within the groove and overlying the outerflange of the rail to be flush therewith, the said vertical flangeproviding an upper extension for the outer flange of the rail,interlocking means between the horizontal flange and the inwardlydirected projection whereby to hold the extension member in overlyingflush engagement with :the outer flange of the rail, the said extensionadapted 10 have a weathering engagement with a Weatherstrip carried by adrip shield formed on the window frame.

4. The structure according to claim .3, wherein the interlocking meansincludes a hook formed upon the horizontal flange that has hookingengagement beneath the inward projection.

5. The structure according to claim 3, wherein the upper part .of thevertical .flange is offset inwardly, the

said L-shaped member being slidably engaged with the rail in ahorizontal manner for disposing the marginal edge of the horizontalflange within the groove and the interlocking means in underlyingengagement with the inward extension.

6. In combination with a window device including a frame and a pluralityof horizontally pivoted sash disposed in the frame, the sash beingidentical in construction and including each an upper rail having innerand outer flange members, means detachably engaged with an upper railwhereby to convert either sash for use as an uppermost sash, .the saidmeans constituting an upper extension for the outer flange whereby toweather against a Weatherstrip formed upon the Window frame when thesash are shifted to a closed position.
